CUTTING-MACHINE.

Specification of Letters Patent.

Patented Feb. 23, 1915.

To all whom it may concern Be it known that I, RALPH C.'SIM1\IONS, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Cutting-Machines, of which the following description, in connection with the accompanying drawing, is a specification.

This invention relates to machines for cutting sheet material, and particularly to machines for cutting out'blanks from such material by means of a die. In a common type of machine of this character the die is subjected to pressure between members that have provision for relative movement so as to force all portions of the cutting edge of the die simultaneously through the stock.

An important object of the present invention is to effect an improvement in machines of this general type whereby less power will be required to operate the machine and the latter may be made lighter in construction without the danger of excessive strain upon the mechanism.

lVith this end in view the invention contemplates the provision of a machine which will operate to force different portions of the cutting edge of the die successively into or through the stock, thereby performing the cutting operation in a progressive manner.

It further contemplates, as one preferred embodiment of means for effecting the general object in view, an arrangement whereby a die is placed with its cutting edge opposite and preferably in contact with material to be cut, and is then subjected to pressure upon its inactive face, first at or near one side of the latterand then at oints successively approaching the other side, whereby the cutting edge is forced progressively and evenly through the stock.

A more particular object of the invention is to effect improvements in a type of machine used extensively at the present time especially for cutting out blanks from upper leather in the manufacture of boots and shoes, and known commercially as the clicking machine.

In the operation of this machine, as usually constructed, the die is subjected to pressure, 1n the nature of a, quick blow, by the relative approach of cooperating presser members between which the die 1s placed. My invention, in its illustrated preferred embodiment, provides for relative movement of such presser members in the path of their approaching movement, whereby diflerent portions of their op osed faces successlvely reach their limit 0 approach and the die between such faces is thus subjected to pressure pro ressivel alon its cuttin edge from one si de to th: OtllBl? g In the commercial'type of clicking machine the presser member is secured at one end to a post that is mounted to reciprocate in vertical bearin s at the rear of the bed, and projects free y over the bed, so as to contact with the die on the downward move ment of the post. It is a natural incident to such a construction, and it has been found true n practice, that the presser member near 1ts o uter projecting end is less certain and positive in its action upon the die than at portions that are nearer to the post. This is because of the manner in which the member is mounted and o erated, whereby portionsthereof farther rom the post are subect m greater degree to that slight unavoidable upward swin of the member in its operation upon the die, which is incident to the wear of the post in its bearings, the inertia of the member on its sudden downward movement, and the tendency of the frame of the machine, however strongly constructed, to spring somewhat under the action of the presser member on the die. The difficulty is increased when a large'die is in use, since in such a case one portion of the die may be located near the rear of the bed where the ran e of yielding movement of the presser mem er is small and another portion may be near the front of the bed where it is encountered by the outer free end of the presser member at a point considerably farther from the post where the range of yielding movement .is relatively large. To avoid the difiiculty it is customary to raise slightly the front edge of the cuttin block and to var as necessary the limit 0 relative aplproac ofthe resser member and bed. 1; has been foun however, that when proper adjustments have been made for the use of a large die the machine will not operate in its most effective manner with a small die without further adjustment, and vice versa, and that the difliculty is exaggerated where a cutting block formed of some hard and resistant material such as metal or a composition thereof is in use. With the object of avoiding these difficulties my invention embodies a construction wherein the die is subjected at all ortions of its cutting edge to sufficient positive pres sure to assure a clean cut through the stock without unduly increasing the pressure or resistance where any portlon of the cutting edge encounters the hard material of the block. An important feature of such a construction consists of means whereby one of the cooperating presser members has provision for yielding movement in the path of relative approach of said members a ainst resistance suitably proportioned to e 'ect a positive cut through the stock but to yield to the reater pressure of the die against the sur ace of the block.

In its referred embodiment the invention contemp ates further provision whereby the presser member, while yieldin to a certain degree of pressure encountere at one portion of the die, will successively bring increased pressure to bear upon other portions of the die, thereby effecting the cutting operation in the progressive manner previously referred to with a relatively small amount of power and without the danger of excessive strain upon the machine under any working conditions.

Another ob'ect of the invention, in connection with t e use of a projecting presser member mounted to swing yieldin y in the path of its movement toward the ed, is to provide means to compensate suitably for the difference in effective action of the memher at different distances from its pivotal point due to the differences in effective leverage. Such means comprises preferably a toggle device combined with some resistance member such as a sprin so arranged that the toggle will approac its straight line position, or position of least resistance, as the presser member contacts with the die at points successively nearer to the post, or in other Words, as the effectiveness of the member, considered as a lever operating against the resistance of the spring, decreases. This assures that all portions of the die shall be subjected to substantially the same pressure. Provision is also made for initiating positively the movement of the toggle at a predetermined point 111 the approach of the presser member to the bed in case a die is not so located as to receive the contact of that portion of the member which is normally nearest to the plane of the bed. As a result of this the die will receive substantially the same pressure wherever it may be located u on the bed and whatever the size of the 'e may be. The features detailed combine to prevent that rapid wear of the cutting block and the consequent necessity of resurfacing often encountered in cutting machines, and also make it feasible,

in view of the comparatively light and even pressure to which the die is Sub ected, to use a block formed of some composition of metal, which is less cumbersome than blocks made of wood or similar material and is not so easily scarred.

A further feature of the invention resides in the provision in a machine of the type referred to of means for adjusting the position of the cutting bed with reference to the presser member, and means conveniently located for indicating the proper position for the bed whatever may be the depth of the die in use.

A further object is to provide simple and effective means for actuating the mechanism that operates the presser member.

Other features and objects of the invention will appear from the following dctailed description and will be pointed out in the claims.

The accompanying drawing is a view in side elevation and artly in vertical section of a machine embo ying a preferred form of the invention.

Supported upon the front portion of the frame 2 of the machine is the table 4 which is formed with flanges 6 arranged to slide in vertical guideways 8 on the frame. Seated at one end upon a projection of the frame is the spindle 10 provided with a hand wheel 12 and having screw threaded engagement with the table at 14. The spindle thus provides a means of support and of vertical adjustment for the table. Resting upon the table is the cutting block or bed 16 which in this machine may be, and preferably is, formed of some composition of metal. A clamp 18 upon the table serves to hold the cutting block in place. The block or bed is intended to support, in the operation of the machine, a sheet of material 20, which may be a portion of upper leather from which blanks are to be cut for use in the manufacture of boots and shoes, and a die 22 which isto be placed in the desired position with its lower or cutting edge in contact with the stock and its upper or inactive face arranged in position to receive the contacting pressure or blow of an operating member to be described.

Mounted for turning and reciprocating movement in bearin s 24 and 26 of the frame is a post 28 w ich is swiveled at its lower end upon a stud 30 and rests u on ball bearings 32 carried by the stud. he stud 30 has pivoted thereto an arm 34 which forms a stra encircling the eccentric 36 on the operating shaft 38. This shaft has mounted loosely upon one end thereof an operating pulley 40, and a clutch is provlded by which this pulley may be connected with the shaft at the will of the operator, so as to impart reciprocatory movement to the post 28. This clutch is preferably such as .to impact at each actuation thereof a single reciprocation to the post 28, but its features are not shown in detail, since this member, and likewise the brake device 42 which is arranged to stop the post automatically at the upward-limit o f 1ts movement, may be the same as used n the commercial type of clickin machine and as shown, for example, in nited States Letters Patent 921,503 granted to Arthur Bates, May 11, 1909. A lever 44 has connections for tripping or actuating the clutch 18 arranged to be operated by means which will be subsequent described.

Mounted upon t e post 28 so as to turn or reciprocate bodily therewith is the d e operating arm or presser member 46. This member is pivoted to the post-at 48 so that it may have a swinging movement in the path of its movement toward or from the cutting bed. Encircling the post is a spring 50 which is mounted between the fixed collar 52 and the movable collar 54. Carried by the post also is a toggle device which comprises a member 56 partly surrounding the post and pivoted thereto and forming one arm of the toggle,and links 58 pivoted to this am at one end and at the other end pivoted to the collar 54 and forming the other member of the toggle. Links 60 connect the toggle with the upper portion of the presser member. Although only one of the lmks 58 and 60 respectively is shown on the drawing, it will be understood that simllar llnks will preferably be arranged on the other side of the machine. It will be seen that with this construction, the presser member is supported yieldingly for swinging movement about its pivot 48, and is arranged in a predetermined normal position with res ect to the plane of the cutting bed. Pre erably this member will be arranged as shown with its lower or contactin surface somewhatinclined to the lane 0 the bed and with the forward portion of this surface nearer the bed than the rear portion. The normal incline of this member with respect to the bed will depend, it is clear, upon the posit] on of the collar 54 upon the (post, and an adjusting screw 62 is rovide for varying .the position of this col ar and consequently the normal predetermined inclination of the lower surface of the presser member'with respect to the bed.' The presser member will be formed preferabl with a contactin surface which is somew at curved in .the irection of the length of the member, as shown at 64. i

a; It will be understood that the presser member is intended to receive its swinging movement about the pivot 48 in opposition to the action of the spring and toggle through the resistance encountered by the contact of this member with the die on the downward movement of the post. With the presser member inclined, as shown, its lower surface will contact first with that side of the die which is nearer the front end of the member, and will then, as the presser member continues its downward movement and swings about its pivot, contact with the die at points successively approaching the rear. In this. operation the presser member acts as a lever arm against the resistance of the spring and toggle, and it will be apparent that the effective length of this arm is constantly decreasing as the member contacts successively with different portions of the die. At the same time, however, the toggle is approaching its straightened position so that the normal descreasing effectiveness of the lever is substantially compensated for by the decreasing resistance of the toggle and spring. The purpose and effect of this arran ement is that the presser member shall sub ect the die at all ortions of its cutting edge to substantial y uniform pressure against the stock and bed. It will be evident, however, that with the arrangement so far described, if the die were placed upon the stock near the front of the cutting bed, the general average of pressure thereupon would be less than if it were placed near the rear of the bed, since the eifective length of the lever arm at the point of primary contact of the presser member with the die would be greater in the former instance. To obviate this diificulty, I have provided means for initiating the upward swinging movement of the presser member at a pre determined point in the approach of this member to the bed. This means comprises an arm 66 projecting upwardly from the toggle member 56 and formed with an inclined cam portion 68 which is arranged to engage with an abutment, such as a roller 70 mounted in a forked projection 72 of a collar 74, on the downward movement of the post. The collar 74 rests upon the upper portion of the frame and loosely encircles the post and is restrained from upward movement by means of a clamp 76. The arm 66 is arranged between the projections of the fork 72 so that on a swinging movement of the presser member and turning of the postto one side or the other, the collar will be carried therewith and the roller will thus be presented for contact with the cam surface 68 in any lateral position of the presser member with respect to the bed.

The cam member 68 is so arranged with cam comes in contact with the abutment, and the ositive mechanism for operatin the togg e will thus be inefi'ective. If the 'e is placed, however, somewhat toward the rear of the bed, the contacting face of the presser member because of its inclination will not meet the die so soon in the downward movement of the member, and in such case the cam 68 first encounters the roller 70 and the bending of the toggle and swinging movement of the presser member are initiated before the latter comes in contact with the die. The toggle will thus be somewhat straightened before the resistance of the die is encountered, and the resistance of the toggle and spring will be adjusted positively in proportion to the shorter effective leverage of the presser member by virtue of its contact with the die at a point somewhat nearer to the post. Through this means the presser member will subject the die to substantially the same average pressure wherever the die may be located upon the bed. This assures a clean cut through the stock and prevents that rapid wear of the cutting bed which is encountered where one portion of the die is subjected to a greater pressure than another portion. It also makes it feasible to employ a cutting bed formed of some composition of metal without destructive effect upon the cutting edge of the die. It should also be noted that the positive means provided for swinging the presser member would prevent the forward portion of this member from coming in contact with the bed in case the machine should be operated accidentally with no die in position, an action which otherwise might occur in view of the forward inclination of the presser member.

The starting device for actuating the clutch comprises a rod 78 connected at one end to the lever 14 previously referred to and at its other end to a lever arm 80 pivoted upon the frame of the machine and held by a spring 81 at the limit of its downward movement. Mounted upon the forward end of the presser member is a handle 82 by which this member is swung to difl'erent ositions above the bed in the manner usual in this type of machine. For moving the lever 80 upward and thereby actuating the clutch, I have provided a novel arrangement which comprises a flexible cord 84 connected with the lever and having connection also with a pivoted portion 86 of the handle 82. This cord is guided by a pulley 88 mounted on a holder 90 which is swiveled in the upper end of the post 28 and is held in swiveled position by a screw 92, the reduced end of which engages in an annular groove in the depending stud 94 of the holder.

This provides a simple and convenient arrangement by which the operator may first swing the resser member to operative position and t on by a slight pressure or gripping movement of his hand effect a pull upon the cord and thereby actuate the clutch. As the post descends, the pulley 88 is of course carried downward therewith and the cord is therefore loosened so that the parts of the tripping arrangement at the rear of the machine necessarily return to their starting position through the action of the spring 81 at the beginning of the downward movement of the presser member. The pulley 88 is provided with deep flanges so as to prevent the cord when loosened from becoming disengaged therefrom. Since the holder for the pulley is swiveled in the top of the post, the pul ey may turn somewhat to one side or the other in proportion to the swinging movement of the presser memher to one side or the other with respect to the'bedp In order to indicate the proper point for the adjustment of the table 4, especially where dies differing in height are in use, I have provided a gage which consists preferably of a bent rod 96 swiveled in a socket 98 in the frame and having an end portion 100 projecting in a lane which the upper face of the die shoul meet on the adjustment of the table and parallel to the plane of the bed. The gage thus indicates the proper position for the upper face of the die with reference to the limit of operative movement of the presser member toward the bed. The gage. when not in use, may be swung aside out of the range of operative movement of the presser member, or may be easily removed from the machine.

The principal features of operation of the machine have been pointed out in the preceding description. To recapitulate briefly, the operator, after adjusting the table to proper position to suit the depth of die in use, arranges upon the bed a sheet of material such as a piece of upper leather and places the die in a suitable position thereupon with its cutting edge in contact with the material. By means of the handle 82 he then swings the presser member to position over the die, and by a slight compression of his hand moves the portion 86 of the handle so as to pull upon the cord and actuate the clutch. By the clutch operated means the presser member is then moved quickly downward toward the bed, and if the die is arranged near the front of the bed the presser member contacts with the die before the cam 68 becomes efiective to cause the arm 66 to swing and operate the toggle. The presser member contacts with the die first on that side which is nearer the forward end of said member and on its continued downward movement begins to swing upwardly about its pivot 48 against the resistance of the spring and toggle. This brings other portions of the curved surface 64 downward in contact with the die and thereby brings pressure out. At the same time that portion of the blade which first becomes efiectiye ls relieved of any excessive pressure WhIOh would tend to force the blade unduly into the surface of the bed. The arrangement of the spring and toggle device, as previously pointed out, assures that all portions of the I die shall be subjected to substantially the same pressure. In case the die is placed somewhat toward the rear of the bed, the cam 68 and roller 7 become effective to begin the straightening of the toggle before the presser member contacts with the die. This assures, as previously explained, that the die shall be subjected to substantially the same pressure wherever it is placed upon the bed. After the cutting operation the presser member returns immediately and automatically to ts starting position at the upward limit of its movement, and may then be swung aside to permit ,the die to be placed in some other position upon the stock, when the above described operations may be repeated.

Although I have described a machine in which a die is placed with its cutting edge resting upon a sheet of stock supported upon a stationary cutting bed and a presser member is moved into contact with the die, it should be understood that I contemplate simply relative movement of the presser member and bed, which constitute, in effect, cooperating presser members with respect to which the die and material to be cut may be arranged in various ways to effect the cutting operation. It should be understood also that the invention in many of its aspects is not limited to the other precise features and details of construction shown in the illustrated preferred embodiment thereof, but is susceptible of various other embodiments.
